Flood Zone Terminology

FW (Floodway) An area that includes the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water-surface elevation by more than a designated height. (Note: this area is normally in Zone AE.)
EASE (Flowage Easement Area) An area within a community, usually bordering a stream, that has more restrictive floodplain development criteria imposed upon it by the governing body (town, city, etc.) than the criteria imposed as a prerequisite to participation in the NFIP. (Note: Unlike the floodway, this area may overlap any other flood zone.)
STATE (State Encroachment Area) An area within a community, usually bordering a stream, that has more restrictive floodplain development criteria imposed upon it by the state, than the criteria imposed as a prerequisite to participation in the NFIP. (Note: Unlike the floodway, this area may overlap any other flood zone.)
